Coming from a country like India, I have a different opinion. We have FPTP but the voter turnout is somewhat higher (60-85% depending on the state) compared to the US. There are a large number of political parties but only three or four of them can be considered national (have representatives in more than one states). Most of the parties are local to a state or a relatively small community (often a caste) and tries to appease their voter base as much as possible.

This system definitely allows smaller communities to be heard on the national stage, but it also frequently leads to situations where no single party or pre-election coalitions have enough representatives to form a government (they need at least 50% seats). As a result, coalitions are often formed between unlikely partners who are ideologically worlds apart. Parties forming a coalition at a state level while disparaging their partner at the federal level is quite common, and the number of hoops the politicians jumps through to justify their positions is hilariously sad.

Due to this coalition politics, often important legislation can't be passed as it is difficult to make any progress while satisfying all the partners. The government is also prone to "blackmail" from coalition partners who often threaten to withdraw support unless their demands are met. In a two-party system, at least things move. In a multi-party scenario, there is always a risk of a complete deadlock.
